Songs

Only male Carolina Wrens sing—a series of several quick, whistled notes, repeated a few times. The entire song usually lasts less than 2 seconds and the notes are usually described as three-parted, as in a repeated teakettle or germany. Each male has a repertoire of up to several dozen different song variations. He'll sing one of these about 15 times before changing his tune.

Calls

Carolina Wrens have a large repertoire of calls, including loud repeated rasping, chattering, and a rising and falling cheer.

Other Sounds

When they hear an intruder encroaching on their territory, male Carolina Wrens sometimes fly in short bursts, slamming hard into surfaces with an audible whirring of their wings. Wrens in Florida "drum" palmettos in this way, apparently in an attempt to get intruders to show themselves.
